- If ``self`` is either ``+infinity`` or ``-infinity``, the result is ``True``.
- If ``self`` is either ``+0`` or ``-0``, the result is ``False``.

For complex floating-point operands, special cases must be handled as if the operation is implemented as ``bool(real(self))`` and ``bool(imag(self))``.
For complex floating-point operands, special cases must be handled as if the operation is implemented as the logical AND of ``bool(real(self))`` and ``bool(imag(self))``.
